ATTACHMENT FOB GRAIN-BINDERS.

SPECIFICATION forming'part of Letters Patent No. 758,161, dated April 26, 1904. Application filed September 16, 1903. Qerial No. 173,454. (No model.)

T0 at whom, it may concern:

Be it known that we, JAMES H. WILLIAMS and GEoReE'B. EVANS, citizens of the United States, residing at Dodgeville, in the county of Iowa and State of YVisconsin, have invented a new and useful Attachmentfor Grain-Binders, of which the following is a specification.

This invention relates to attachments for grain-binders; and it has for its object to provide certain improved means for preventing the clogging of the needle at the point where it passes through the slot in the breastplate just before engaging the knot-tying mechanism and the stoppage of the machine necessary for the purpose of clearing out the same.

Most grain-binders while operating in grain that is dry and in good condition will progress uninterruptedly so far as the operation of the needle is concerned. Under less favorable conditions, howeverthat is, when the grain is wet, tangled, matted, and down-it frequently occurs that the gavel carried forward by the needle is not thoroughly separated from the adjacent grain, but that severalstalks of grain will be carried along, theends of the same being intertwined with'the ends of the gavel, while such superfluous straws will lie against the back of the needle. The consequence is that when the breastplate is reached such superfluous straws will clog in the slot of said breastplate, thereby hindering the progress of the needle and eventually making it necessary to stop the machine temporarily for the purpose of clearing out the slot in the breastplate. It is in order to avoid this disadvantage and the loss of time resulting thereupon that we have devised our improved attachment, which is in the nature of a serrated knife or cutter adapted to be suitably attached to the breastplate, the construction and arrangement of said cutter being hereinafter fully de-.

scribed, and particularly pointed out in the claims.

In the accompanying drawings, Figure'l'is a diagrammatic view illustrating the rear end of the knotting devices, needle, breastplate, binding-table, and related parts, showing the application of our invention. Fig. 2is aperspective view showing the cutter which constitutes our invention detached from the machine. Fig. 3 is a plan view of said cutter viewed from the opposite side.

Corresponding parts in the several figures are indicated by similar numerals of reference.

In the accompanying drawings, 1 designates the binder-table; 2, the main driving-wheel for the knotting, holding, cutting, and ejecting devices, and 3 is the breastplate, which is a shield lying between the bundle-receptacle and the knot-ting and holding devices, said shield being slotted to permit the passage of the point of the needle in laying the twine around the gavel and having the cheek-piece 4. Adjacent to the upper end of the slot 5 is suitably secured a cutter 6, having a plurality of teeth 7, the outer ends of which are blunt, as shown at 7 while said teeth are provided with inclined cutting edges '7, and these cutting edges are to be so disposed'with relation to the needle that the latter in its forward movement will pass directly under and practically in contact with the blunt ends of the teeth of said cutter. It will thus be seen that while the teeth of the cutter do not in any way interfere with the needle or the gavel they will unfailingly cut any straws the ends of -which may have become intertwined with the ends of the gavel and which thus will be carried with the needle and upon the rear side of the latter. All possibility of such tangled straws becoming clogged at the end of the slot in the breastplate is thus avoided.

The knife or cutter itself, as illustrated in Fig. 2, is preferably provided with a flange 8, having perforations 9 to receive bolts or other suitable fastening means.

We do not wish to confine ourselves to the precise'structure herein exhibited, but reserve the right to any changes, alterations, and modifications which may be resorted to within the scope of our invention and without departing from the principle or sacrificing the utility of the same. 1 1

Having thus described our invention, we cl aim 1. In a grain-binder, a needle, and a cutter supported to engage the back of said needle between the side edges thereof.

2. In agrain-binder, a needle, a cutter having a blunt edge to engage the back of the neeand adapted to engage the back of the latter. dle between the side edges of the latter, and In testimony that we claim the foregoing as a sharp edge facing the point of the needle our own we have hereto aflixed our signatures when the latter is retracted, and means for in the presence of two witnesses.
